Biotherm

In the early 20th century, the French doctor Jos Jullien discovered mineral thermal spring waters under Pyrenees mountain in the southern part of France which contained thermal plankton, supposedly a key to healthy skin and a potent skin rejuvenator.

In the years 1940-50, Dr. Jos Jullien,[3] from Joyeuse in Ardeche (France), noticed the presence of a particular substance on the surface of the thermal waters of Molitg-les-Bains.

With Jeanine Marissal, he worked on the potentials of this substance that could be integrated towards creating a cosmetic formula.

In 2014, Leighton Meester was appointed as the new global spokesperson for the skin care brand Biotherm.
